装虚拟机时空间划小了,于是又加了 5G 的空间,折腾了半天,挂上去了。整理下弄个笔记,备用。
- 添加磁盘,查看磁盘状况

从查询结果看出,多了一个/dev/sdb的盘
- 用 fdisk 对/dev/sdb 进展分区
[root@db1 /]# fdisk /dev/sdb Command (m for help): n Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-652, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-652, default 652): Using default value 652
Command (m for help): w
The partition table has been altered!
Calling ioctl to re-read partition table. Syncing disks.
再次查看分区状况,多出来一个/dev/sdb1 的区,这个 1 是我们在前面指定的,假设我们指定 2,就变成 sdb2 了。
[root@db1 /]# fdisk -l

假设创立完之后,/proc/partitions 查看不到对应的分区,使用 parprobe 命令刷一下就可以了:
[root@web1 ~]# cat /proc/partitions major minor #blocks name
